Synopsis Rather typical weather pattern for june will persist into
this week. Dry, with near seasonable temperatures for a while.

Marine stratus along the coast will vary in extent and coverage.

Inland, mostly clear, but will see varying degrees of marine
stratus, primarily from portland area downstream to kelso.

Short term Today through Wednesday... The CWA will remain in a
fairly typical summer-time onshore flow pattern through the next
several days. Surface high pressure will remain over the NE pacific,
while thermal low pressure continues over the northern california and
southern oregon coast. The onshore flow will become breezy during the
afternoon and evening hours each day. Today and Monday look to be
near repeats of yesterday. Marine stratus along the coast will again
build into portions of the northern willamette valley, including the
pdx vancouver metro area. Some patchy radiational stratus may form
over the central and southern valley, but coverage should be much
less than further north. The morning clouds will burn back offshore
during the afternoon and evening. Expect highs over the interior
lowlands in the upper 70s to low 80s, with mainly 60s at the coast.

By tue, an upper level trough over the gulf of alaska will be pushing
south toward the pac NW coast. This will nudge the NE pacific high
southward and decrease heights over us a bit. The fcst models
continue to indicate that the weak remains of a cold front will move
onshore Tue morning. This will deepen the marine layer, bringing more
extensive cloud cover and possibly some coastal drizzle or light
showers. Highs should end up several degrees cooler on Tue as well,
with the interior seeing highs in the mid 70s. The upper trough will
continue to dig south on wed. This should continue to strengthen the
onshore flow and result in a fairly extensive morning stratus push.

Temps on Wed should cool again by a degree or two compared with tue.

Pyle

Long term Wednesday night through Saturday... Deterministic
guidance continues to diverge in the extended period, but the general
pattern continues to show a deep upper level trough building into the
western us. This will maintain our onshore flow pattern and bring
seasonal temps. The cloud forecast will continue to sound like a
broken record with periods of morning clouds and afternoon Sun inland
and stratus along the coast. Rain chances continue to remain low
through the forecast period, but cannot rule out a stray shower in
the south washington cascades on Thursday as the base of the upper
level trough moves onshore. 64

Aviation Stable dry westerly flow aloft, with thin cirrus aloft.

Low MVFR ifr marine stratus persists offshore. Mix of MVFR and ifr
stratus along the coast, but that will thin and burn off this am for
most areas, with stratus persisting from about seaside northward.

Farther inland, MVFR stratus extends through the cowlitz and lower
columbia valley, and far northern willamette valley. This stratus
will break up and burn out between 18z and 20z today.VFR this
evening, but low MVFR ifr marine stratus will retake the coastal
strip later, with MVFR stratus spreading up columbia river and into
the interior valleys again overnight.

Kpdx and approaches... Variable high clouds with stable westerly flow
aloft. MVFR stratus over ops area, with tops around 2500 ft. This
stratus looks to burn out between 18z and 19z today. Afterwards,
vfr, but MVFR stratus returns Mon am. Rockey.

Marine A persistent weather pattern with high pres across the
coastal waters and thermal low pres over northwest calif will
maintain northerly winds through this week. The pressure gradient
will be tightest south of cascade head in the afternoon and evenings
where gusts of 20-25 kt are likely. Buoy 50 has been reporting gusts
around 25 kt overnight supporting the current small craft advisory.

The gradient will weaken a little this morning allowing the winds to
fall below advisory levels through early this afternoon. The winds
should pick up in the afternoon with gusts back to around 25 kt
through this evening. The persistent north winds may result in steep
'square' seas around 6 feet at times. The wind gusts should remain
below 25 kt north of cascade head. ~tj

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds 3 pm to 10 pm today for the
coastal waters from cascade head to florence.
